what is the use of choke on tube light fitting

Answers were Sorted based on User's Feedback



what is the use of choke on tube light fitting..

Answer / dileep

At the time of starting a tube choke gives rise to high
voltage by di/dt nearly 1000 volts by starter ON-OFF
function rate of change of voltage becomes high due to
inductance of choke. This high voltage starts ionization of
gas in the tube. Once gas gets ionised and starts
conducting then starter gets out of circuit and circuit is
completed only through choke which now share voltage(limit
voltage) for tube because after esabilishing ionization now
to maintain it only nearly half of the voltage is required.

Answer / manish tailor

The function of choke is to provide high voltage enough for
ionization to take place in a tube light and after
establishment and substenance of ionization, limit the
voltage across the tube. That is the reason why a tube
fuses when the choke is shorted.

what is the use of choke on tube light fitting..

Answer / nimish

To start the tubelight. we have to ionise the gas inside
tubelight like murcury which ionise at high voltage around
1000 to 1500 V it is provided by choke.

what is the use of choke on tube light fitting..

Answer / rathnam

the property of the inductor is to oppose the rate of
change of current through it suddenly. At the time of
starting it requires high voltage to ionise the gas (
through creating potential difference between the
electrodes) in the tube so choke creates required potential.
The starter is same as that of a capacitor, to improve the
power factor the total system(connection of R and L) it is
required.

what is the use of choke on tube light fitting..

Answer / ramesh

The choke acts a regulator and controls the current flow
thro' the flourescent tube.
